Square - the default for most small businesses, especially in-person.** No monthly fee, free POS app, hardware you can buy as you need it, invoicing and ACH included. Flat 2.6% + 15¢ in person, ~3.3% + 30¢ online. The flat rate isn't the cheapest, but setup takes an afternoon and you'll never get a surprise statement. Best if you're under roughly $10-25K/month.\n\n**2. Stripe - if you're online-first or selling software/subscriptions.** 2.9% + 30¢ online, ACH at 0.8% capped at $5, no monthly fee. Best developer tooling and documentation of anyone, strong international support, excellent recurring-billing handling. Overkill if you just need to swipe cards at a counter.\n\n**3. Helcim - the one to switch to once you have real volume.** Interchange-plus pricing instead of flat rate, so you pay actual card-network cost plus a small fixed markup. Effective rates average ~1.93% + 8¢ in person and ~2.49% + 25¢ online, and the markup drops automatically as volume grows. No monthly fee, no contract. Typically 20-40% cheaper than Square or Stripe above ~$5-10K/month. This is my pick if you're processing $10K+/month and willing to read", "answer_truncated": true, "measurement": "One answer from one engine on one date.
